The Mouse, the Frog, and the Hawk

A Mouse and a Frog struck up a friendship; they were not well
mated, for the Mouse lived entirely on land, while the Frog was
equally at home on land or in the water. In order that they might
never be separated, the Frog tied himself and the Mouse together by
the leg with a piece of thread. As long as they kept on dry land
all went fairly well; but, coming to the edge of a pool, the Frog
jumped in, taking the Mouse with him, and began swimming about and
croaking with pleasure. The unhappy Mouse, however, was soon
drowned, and floated about on the surface in the wake of the Frog.
There he was spied by a Hawk, who pounced down on him and seized
him in his talons. The Frog was unable to loose the knot which
bound him to the Mouse, and thus was carried off along with him and
eaten by the Hawk.
